Srinagar, India (CNN) -- Authorities were searching Tuesday for suspects who gunned down two teenage sisters in a north Kashmir town.

The sisters, ages 19 and 17, were killed in the town of Sopore, in what police called the first killing by militants this year after a violent summer of clashes.

The protracted summer unrest last year claimed 110 lives and left hundreds others wounded.

The young girls were marched out of their home by gunpoint Monday night, police said.

"The militants later shot them in cold blood," Sopore police chief Altaf Khan said, "The bodies of the slain sisters were found some distance away from their home. A manhunt has been launched to nab the murderers, two of whom we have already identified."
